Description

This Mushroom and Spinach Frittata is a wholesome, savory egg dish packed with sautéed mushrooms, fresh spinach, zucchini, and optional cheese. Perfect for breakfast, brunch, or a light dinner, this recipe combines the earthiness of mushrooms with vibrant vegetables and a hint of garlic. Cooked first on the stovetop and finished under the broiler for a golden top, the frittata is easy to prepare and customizable with your favorite cheese and garnishes.


Ingredients

Scale

Vegetables

  • 1 cup mushrooms (cremini or portobello, sliced)
  • 1 cup spinach (fresh, or frozen and thawed/drained)
  • 1 medium zucchini, thinly sliced
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced

Egg Mixture

  • 6 large eggs
  • Salt and pepper, to taste
  • ½ cup shredded cheese (cheddar, mozzarella, or goat cheese; optional)
  • A pinch of red pepper flakes (optional)

Other

  • 1 tablespoon olive oil
  • Optional garnishes: fresh parsley or chives, sour cream or Greek yogurt


Instructions

  1. Prep Your Ingredients: Thinly slice the zucchini, finely chop the onion, clean and slice the mushrooms, prepare the spinach by rinsing fresh or thawing frozen and draining excess moisture, and mince the garlic.
  2. Sauté the Vegetables: Heat an oven-safe skillet over medium heat and add olive oil. Sauté the chopped onion for 2 to 3 minutes until translucent. Add minced garlic and cook for an additional 1 minute until fragrant. Stir in the mushrooms and cook for about 5 minutes until they turn golden brown. Add the zucchini slices and sauté for 3 to 4 minutes. Finally, add the spinach and cook just until it wilts. Season the vegetables with salt, pepper, and optional red pepper flakes to taste.
  3. Whisk the Eggs: In a mixing bowl, crack the eggs and whisk until frothy. Add a pinch of salt and pepper. If using cheese, stir in half of the shredded cheese into the eggs for extra flavor and meltiness.
  4. Combine Eggs and Vegetables: Spread the sautéed vegetables evenly in the skillet. Pour the whisked egg mixture over the vegetables, gently stirring once to combine. Sprinkle the remaining shredded cheese on top evenly.
  5. Cook and Bake: Reduce the heat to low and cook on the stovetop for 3 to 4 minutes until the bottom starts to set. Meanwhile, preheat the oven’s broiler. Transfer the skillet to the oven and broil for 5 to 7 minutes until the top of the frittata is golden and the eggs are fully set. If you do not have a broiler, bake the frittata at 350°F (175°C) for 10 to 12 minutes until fully cooked.
  6. Serve and Enjoy: Remove the frittata from the oven and let it cool for a few minutes. Use a spatula to loosen the edges, then slide it onto a cutting board. Slice into wedges and garnish with fresh herbs like parsley or chives, and optionally add a dollop of sour cream or Greek yogurt before serving.

Notes

  • Use an oven-safe skillet to transition from stovetop to broiler/baking step safely.
  • Frozen spinach must be thawed and excess water squeezed out to avoid a watery frittata.
  • Cheese is optional but adds richness; use your preferred type or omit for dairy-free.
  • If you don’t have a broiler, baking at 350°F (175°C) is an excellent alternative.
  • Adjust red pepper flakes according to your heat preference or omit for no spice.
  • Leftovers can be refrigerated and reheated gently for a quick meal.
